FLUID-GAGE.

Specification of Letters Patent. Application filed August 24, 1912.

Patented Mar. 17, 1914. Seria1No.716,897.

Be it known that; l. .licnny .ll. TAvNnn, a eitizen oi the lnitedStates. residing at Akron, in the county of Summit and State of Ohio,have invented new and useful Improvements in Fluid-Gages, ol' whieh thefollowing is a opeeifieation.

This invention relates to improvements in fluid gages used to determinethe level of a fluid in a receptacle to thereby indirate the quantitycontained therein.

Broadly, the ohjeet of the invention to produce a gage of greatsimplieity, ellieieney and eheapness in which the parts are reduced to aminimum without a dotting the operation of the gage.

More speeilieally, the invention etmtenr plates providin a pair ofhinged members depending in the reeeptaele hinged together at theirlower end and with the upper end of one of the members provided with anin- (heating fing'e adapted to move over a gradnated dial, and a floatprovided with a central aperture to receive the two members, so that asthe float rises with the level of the fluid in the tank the change ofposition of the indicating ti of the, fluid contained in the receptacle.

A still further object, is to provide mechanism whereby the oscillatorymovement of the upper free end of the movable member is el'ianged to arotarv movement for rotat ing an indicating finger at a. point remotefrom the receptacle to indicate on a graduated dial the volume of lluidcontained in the z -eceptaele.

ith the foregoing and other objects in view, {in invention eonsist inthe novel onetru tion. combination and arrangementof pal-ta(-onztitutine' the inveiition to be hereinafter specifically desrribedand illustrat d in the tlCtiUltiPtltlf/lllg drawings which f rm a parthereof wherein is shown the preferred embodiment of the invention, butit is to he understood that ehanges, varialions and modifications can beresorted to which eome within the seope ot' the elaimn hereuntoappended.

Referring to thedrawinga in detail. the reference numeral l. denote; theupper wall of a fluid-re -eptaele which is provided with an op ning andin whieh is mounted a cup shaped n'ieuiher 2 provided in the lower wallthereol' with a slot 5".

I claim:

1. A fluid gage embodying two men'ibers pivotally hinged together topermit the free oscillation of one member, a float provided with anaperture to receive both of said members and arranged when shifted longitudinally 'thereof to oscillate one of said members.

2. A fluid gage embodying :1 depending fixed member formed uponcurvilinear lines, an oscillatory member pivotally hinged to said fixedmember, a float provided with an afhrture inclosin both members andarranged when shifted to oscillate said pivoted member to therebyindicate the volume of fluid contained in a receptacle.

3. A fluid gage embodying a receptacle provided with a slot, a fixeddepending member in said receptacle, an osciilatory member pivotallysecured to said fixed member, the upper end of said oscillatory memberextending through said slot, a graduated dial near said slot, a floatprovided with an aperture to receive said fixed and oscillatory membersand arranged when shifted to oscillate said pivoted member to indicateon said dial the volume of contents in said receptacle.

4. A fluid gage embodying a receptacle provided with a slot in its upperwall, a fixed depending member in said receptacle, an oscillatory memberpivotally united to said fixed member, the upper end of said oscillatorymember projecting through said slot, a graduated dial near said slot, anindex finger carried by the upper end of said oscillatory member, afloat provided with an aperture to receive said fixed and oscillatorymembers and arranged when shifted to escillate said pivoted member to move said indexfinger over said graduated dial;

5. A fluid gage embodying a receptacle provided with a slot in its upperwall, a fixed depending. member in said receptacle, an oscillatorymember pivotally united to .;aid fixed member, the upper end of whichbrojects through said slot, a float provided with an aperture to receivesaid fixed and oscillatory members and arranged to oscillate the latterwhen vertically shifted, a rotar shaft mounted adjacent to said slot, anin ex finger carried by said shaft, and means carried by said oscillat,ry member and shaftto cause a rotation of the latter when the former isosciilated.

6. A fluid gage comprising a receptacle provided with a slot in itsupper wall,& pair of members depending in said receptacle and pivctallyhinged together, one of said members projecting through said slot afloat provided with an aperture adapted to receive said members and whenshifted vertically to oscillate the member projecting through aid slot,a shaft mounted ad jacent to said s ot and engaging said oscillatorymember, indicating means carried b said shaft, said shaft arranged to berotate by the said pivoted member when the latter is oscillated.

provided with a slot in its upper wall, a pair of members depending insaid receptacle and pi\ otaily united, one of said members projectingthrough said slot, an index finger on the free end of said member, agraduated dial near said slot, a float provided with an aperture toreceive said depending members, and arranged when vertically shifted tooscillate said pivoted member, a shaft mounted near said slot,indicating means carried by said shaft, a graduated dial positionedadjacent to said indicating means, and means connecting said shaft andoscillatory member where iy the oscillations of the latter rotate theformer and said indicating means.

8. A fluid gage comprising a receptacle provided with a slot in itsupper Wall, a pair of members depending in said receptucle and pivotailyhinged together, one of said members projecting through said slot, saidmember provided above said slot with an opening, a float provided withan aperture adapted to receive said members and when shifted verticallyto oscillate the mem ber projecting through said slot, a shaft mountedadjacent to said slot and provided with a spirally-formed portionextending through the opening in said oscillatory member, indicatingmeans carried by said shaft, said shaft. arranged to be rotated by saidpl Otttl member when the latter is osrillated.
